摘要

摘要: 为了优化城市公交线路网络, 用定量分析法把城市公交线网优化的目标及约束条件用特定函数表示, 在定义理想方案的基础上, 以目标函数为因素指标集, 以备选方案为论域集, 求出各个备选方案到理想方案的二维距离, 按距离大小对方案排序, 得到城市公交线网优化的最佳方案。优化结果表明, 优化后公交线网利用率增大, 可达性良好, 优化结果符合实际, 该方法是合理可行的。

Abstract: On the basis of considering each factor of urban public traffic line network, the optimization function expression and the restricted conditions of urban public traffic line network were presented. Based on ideal scheme's definition, the schemes were arranged in simple order according to the distance between each scheme and ideal scheme, so the decision-making model for the optimization of urban public traffic line network was presented. Applied results indicate that the method improve the used ratio of urban public traffic line network, optimization results accord to the real situation, the method is feasible.
